Figure 2) Average SST time series.


SST colors correspond to color locations on the map for the most recent weekly SST averages in 2023 (darker dotted-line) and long-term SST averages between 1997-2022 (lighter solid line). The black horizontal line at 17°C is a reference for optimal temperatures during turtle release.
